Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, in particular to a dual-purpose riveted bolt. Background Art

[0002] Riveting bolt technology originated in the 1940s and was initially used mainly in the aerospace industry. This is because it performs well in preload, anti-loosening and anti-fatigue, meeting the aviation industry's requirements for high performance of connectors. Over time, rivet technology has continued to develop, and researchers have recognized its potential in structural connections and have begun to apply it to fields such as steel structures, rail vehicles and agricultural machinery. These fields require reliable and low-maintenance connection methods, and rivet technology just meets these needs; rivets can generate a large preload due to their unique design, which is crucial to improving the fatigue resistance of connectors. At the same time, this design also ensures good load-bearing characteristics, making the connection more secure; rivet technology effectively prevents bolts from loosening under repeated loads through a specific installation process and structural design, thereby improving the fatigue resistance reliability of the entire structure. This feature is particularly important for applications that are subject to dynamic loads.

[0003] Although traditional dual-purpose riveted bolts can meet basic waterproof fastening requirements, their waterproof performance and fastening requirements are often difficult to guarantee during complex or harsh processing. The waterproof design of some traditional dual-purpose riveted bolts may not be perfect, such as insufficient sealing of riveted and threaded connection parts, which easily forms water seepage channels at the connection. In complex or harsh working environments, under the action of dynamic loads such as vibration and impact, the fastening force of traditional dual-purpose riveted bolts may gradually weaken, resulting in loose connections, which in turn affects the fastening effect. Therefore, it is necessary to optimize a dual-purpose riveted bolt through technological innovation and design optimization. Utility Model Content

[0004] Although traditional dual-purpose riveted bolts can meet basic waterproof and fastening requirements, their waterproof performance and fastening and positioning requirements are often difficult to guarantee during complex or harsh processing. The waterproof design of some traditional dual-purpose riveted bolts may not be perfect. For example, the sealing of the riveted parts and the threaded connection parts is insufficient, which easily forms water seepage channels at the connections. In complex or harsh working environments, under the action of dynamic loads such as vibration and impact, the fastening force of traditional dual-purpose riveted bolts may gradually weaken, resulting in loose connections, thereby affecting the fastening and positioning effect. In order to solve the above problems, an embodiment of the present application provides a dual-purpose riveted bolt, which pushes the conical boss to contact the boss by hitting the round table, squeezes the boss to move outward along the groove of the positioning ring, and a number of positioning cones arranged on the top of the boss penetrate into the connected parts to form a tight connection, which can still maintain the stability of the connection in harsh environments.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problems is as follows:

[0006] A dual-purpose riveting bolt, comprising: a self-tapping thread section and a positioning ring, wherein the positioning ring is arranged at the bottom of the self-tapping thread section;

[0007] Wherein, a nail head is arranged at the top of the self-tapping thread section, a second limiting hole is arranged at the top of the nail head, and the thread diameter of the self-tapping thread section increases slightly from bottom to top. When the thread is inserted along the axis, due to the slight increase in diameter, the thread will gradually and tightly contact the inner wall of the mating hole, thereby increasing the friction and fastening force. This design can effectively prevent the thread from loosening or falling off during use, and improve the stability and reliability of the connection.

[0008] In a possible implementation manner, a sealing washer is installed at the bottom of the nail head, and a water-absorbing cotton is arranged inside the sealing washer. This design ensures the sealing between the nail head and the connection surface. The water-absorbing cotton material can effectively absorb a certain amount of moisture, thereby providing additional humidity control during the connection process to enhance the sealing effect and form a tight sealing layer, thus ensuring the airtightness and watertightness of the connection.

[0009] In a possible implementation manner, the sealing washer is detachable at the bottom of the nail head. This design enables the sealing washer to be easily installed and removed, providing convenience for users; the water-absorbing cotton is composed of multiple layers of fibers, and these fiber layers are tightly intertwined to form a flat sheet structure, which enables the water-absorbing cotton to have good water absorption performance.

[0010] In a possible implementation manner, grooves are evenly formed around the positioning ring and bosses are installed. The bosses are connected in pairs by springs, and a number of positioning cones are evenly arranged at the top of the bosses. When positioning is required, the positioning cones can be inserted into the corresponding positions. Since the bosses are connected in pairs by springs, the entire structure has a certain elasticity. When the object undergoes a small position change during the positioning process, the bosses can adapt to this change through the expansion and contraction of the springs, thereby maintaining the stability of the positioning. This elastic design enables the positioning ring to better adapt to different working environments and object shapes, and improves its scope of application and practicality.

[0011] In a possible implementation manner, a conical tip of a cone part is installed at the bottom of the positioning ring. The conical tip of the cone part is quadrangular pyramidal, and the material is made of aluminum alloy steel.

[0012] In a possible implementation, a punching hole is provided at the top of the nail head, and a number of bumps are evenly arranged around the nail head. A frustum is provided at the top of the punching hole, and a first limiting hole is provided at the top of the frustum. Through the number of bumps around the nail head, when the staff holds the nail head by rotating the self-tapping thread section, the friction force can be increased, so that the hand and the nail head are in close contact.

[0013] In a possible implementation, a connecting rod is fixedly connected to the bottom of the frustum, and a conical boss is provided at the bottom of the connecting rod. The conical boss is thin at the bottom and thick at the top, and is evenly distributed from bottom to top. The evenly distributed conical bosses can enable the connecting rod to evenly transmit the force to the entire structure when subjected to an external force, avoiding damage to the structure caused by the force concentrating at a certain point.

[0014] In a possible implementation, a through hole is provided at the top of the self-tapping thread section, and the connecting rod passes through the through hole to be connected to the frustum and the connecting rod.

[0015] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0016] 1. By the bottom of the sealing gasket contacting the material surface, a tight sealing layer can also be formed with the material surface after contact, thereby ensuring the airtightness and watertightness of the connection. In an extremely harsh environment, some moisture may seep into the sealing port. At this time, the absorbent cotton provided inside the sealing gasket absorbs it and can form a water sealing film to continue maintaining the sealing performance of the bolt, which can meet the waterproof and sealing requirements of IPX7 level, and has strong practicability;

[0017] 2. By hitting the frustum to push the conical boss into contact with the boss, the boss is extruded to displace outward along the groove of the positioning ring, and a number of positioning cones provided at the top of the boss are driven into the connected part to form a firm connection, and the connection stability can still be maintained in a harsh environment.

Specific embodiments

[0026] Next, the technical solutions in the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the present utility model. In addition, the forms of each structure described in the following embodiments are merely examples, and the instrument placement rack related to the present utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0027] This embodiment introduces the specific structure of a dual-purpose riveted bolt. Specifically, refer to Figures 1-3 As shown, a dual-purpose riveted bolt includes a self-tapping thread section 1 and a positioning ring 4. The positioning ring 4 is arranged at the bottom of the self-tapping thread section 1. A nail head 2 is arranged at the top of the self-tapping thread section 1. A second limiting hole 13 is arranged at the top of the nail head 2. The thread diameter of the self-tapping thread section 1 gradually increases slightly from bottom to top. When the thread is inserted along the axial direction, due to the slight increase in diameter, the thread will gradually and closely contact the inner wall of the mating hole, thereby increasing the friction and fastening force. This design can effectively prevent the thread from loosening or falling off during use, improving the stability and reliability of the connection; a sealing washer 3 is installed at the bottom of the nail head 2, and a water-absorbing cotton 11 is arranged inside the sealing washer 3. This design ensures the sealing between the nail head 2 and the connection surface. The water-absorbing cotton 11 material can effectively absorb and retain a certain amount of moisture, thereby providing additional humidity control during the connection process to enhance the sealing effect and form a tight sealing layer, thus ensuring the airtightness and watertightness of the connection; the sealing washer 3 is detachable at the bottom of the nail head 2. This design enables the sealing washer 3 to be easily installed and removed, providing convenience for users; the water-absorbing cotton 11 is composed of multiple layers of fibers, and these fiber layers are closely intertwined to form a flat sheet structure. This structure enables the water-absorbing cotton 11 to have good water absorption performance.

[0028] Example 1:

[0029] When the staff needs to strengthen the sealing performance of the dual-purpose riveted bolt in a humid environment, first place the dual-purpose riveted bolt into the hole to be connected, and then use a wrench or other tools to control the rotation of the nail head 2. The self-tapping thread section 1 will then rotate downward. After reaching the specified position, stop rotating the nail head 2, and then use tools to press the nail head 2 to make the sealing washer 3 move downward, forming a sealed environment between the surface of the connected body and the sealing washer 3.

[0030] Embodiment 2:

[0031] As Figure 1 shown in Figure 2 Based on the same concept as the above embodiment, this embodiment also proposes that: grooves are evenly opened around the positioning ring 4 and bosses 41 are installed. The bosses 41 are connected in pairs by springs 43. A number of positioning cones 42 are evenly arranged on the top of the bosses 41. When positioning is required, the positioning cones 42 can be inserted into the corresponding positions. The connection of the bosses 41 in pairs by the springs 43 makes the whole structure have a certain elasticity. When the object has a slight position change during the positioning process, the bosses 41 can adapt to this change through the expansion and contraction of the springs 43, thereby maintaining the stability of the positioning. This elastic design enables the positioning ring 4 to better adapt to different working environments and object shapes, improving its scope of application and practicability; a conical tip 5 of a cone part is installed at the bottom of the positioning ring 4. The conical tip 5 of the cone part is quadrangular pyramid-shaped and is made of steel-aluminum alloy; a punching hole 12 is opened at the top of the nail head 2. A number of convex blocks are evenly arranged around the nail head 2. A round platform 6 is arranged at the top of the punching hole 12. A first limiting hole 10 is arranged at the top of the round platform 6. Through the number of convex blocks around the nail head 2, the staff can increase the friction when rotating the self-tapping thread section 1 to hold the nail head 2, making the hand in close contact with the nail head 2. The aperture sizes of the first limiting hole 10 and the second limiting hole 13 are the same, and the round platform 6 can be fixed by inserting a pin shaft through the first limiting hole 10 and the second limiting hole 13; a connecting rod 7 is fixedly connected to the bottom of the round platform 6. A conical boss 8 is arranged at the bottom of the connecting rod 7. The conical boss 8 is thin at the bottom and thick at the top and is evenly distributed from bottom to top. The evenly distributed conical bosses 8 can enable the connecting rod 7 to evenly transfer the force to the whole structure when subjected to an external force, avoiding damage to the structure caused by the force concentrating at a certain point; a through hole 9 is opened at the top of the self-tapping thread section 1. The connecting rod 7 passes through the through hole 9 and is connected to the round platform 6 and the connecting rod 7;

[0032] When the staff wants to reinforce the dual-purpose riveted bolt, the staff can use a tool to strike the frustum 6 to push the connecting rod 7 to move downward along the through hole 9, driving the conical boss 8 to contact the boss 41, squeezing the boss 41 to displace outward along the groove of the positioning ring 4, and several positioning cones 42 arranged at the top of the boss 41 are inserted into the connected parts. Then the staff uses a pin shaft to pass through the first limiting hole 10 and the second limiting hole 13 to fix the frustum 6 and fix the boss 41, forming a firm connection and still being able to maintain the connection stability in harsh environments.

[0033] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
